HAS? LOCK.

Leonesa Specification of Letters Patent.

Patented Jan., 1li),

To @ZZ 'whom t may concern Be it known that l, EMMA KNAPP, a citi zen of the United States, residing at Denver, in the county ot Denver and State oi' Colorado, have invented certain new and useful improvements in Hasp Locks, ot which the following is a specification.

rlhis invention relates lto hasp-locks and more particularly to hasp locks of the type in which a key-controlled locking means cooperates with the staple to secure the hasp in place thereon.

It is the primary object oi' the present invention to provide a hasp-lock ot the character above referred to in which the lock is mounted upon a support occupying a. per'- manent position relative to the staple, and has a determinate movement on said support to be brought in cooperative relation to the staple.

Other objects ot the invention reside in providing in connection with the support above referred to, a slide-way for the linear movement ot the lock toward and from the staple, in providing a carrier movable on the slide-way, upon which the lock is movably mounted., in providing a means for the detachable connection of the lock with the carrier, and in providing means cooperative with the carrier to automatically hold it in an adjusted position, and to lift the hasp when the lock is being separated from the staple.

Further objects ot my invention reside in details of construction and novel arrangements of parts, all of which will fully appea-r in the course ot the 'following description made with reference to the accompany ing drawings in which like characters of reference designate correspondingparts throughout the several views,v and in whichligurc 1 represents a side elevation ot the cooperating members of my improved hasp-loclr in its open condition;

Figure 2, a similar view of the hasp lock with its members in the locked position;

Figure 3, a partially sectional plan view taken on the linev 33, Figure 1;

Figure il, an enlarged detail view of the means tor fastening the lock upon its carrior7 taken along the line L-i, Figure 1;

Figure 5, a side elevation ot a modiiied construction of the hasp lock with its members in the locked position;

Figure 6, a similar view partly in section showing the members of the hasp-lock in a partially7 separated position, and

Figure 7, a similar'view showing the keycontrolled lock in the position it occupies when the hasp is removed from the staple.

Referring first to Figures 1 to i, ot the drawings, the reference characters 2 and 3 designate adjoining parts of'two related object-s fastened together by the hasp-lcclt, as for example, a door and its casing, or a box and its lid.

My improved hasp-lock comprises a staple 4 mounted on a base plate 5 which by means otl screws or bolts is fastened to one ot the objects, a hasp 6 hinged at the end ot a plate 7 which by similar means is connected to the other object, and a key-operated lock 8 movably mounted with relation to the staple to be brought in locked connection therewith after the hasp is placed in its locking position.

The lock 8 which may be of any suitable construction, comprises a housing containing the usual key-controlled mechanism for the projection and retraction ot a bow or shackle 9 adapted to pass through the staple after the lock is brought to its operative position with relation thereto.

The lock is movably mounted on a support which for convenience in construction may be formed integrally with the base plate ot the staple.

ln the construction shown in Figures 1 to 3 of the drawings the support consists et' a tongue 10 projecting troni the base plate oi the staple in substantially parallel relation thereto and adapted to sliding-ly support a carrier 12 upon which the lock is mounted.

The carrier consists ot avblock having a slot 'for itsv sliding connection with the tongue whichis bent upwardly at its free end to provide a stop 12 limiting the outward movement ot the same.

A plate 13 spaced 'from the upper surface of the bloclr has a plurality of openings 13a to receive correspondingly positioned headed studs lll on the under side ot' one of the articulated members of a hinge 15 to the other i Aand it has at its opposite end a lip 18 which under the same condition is engaged by the end of an arm 19 which has a resilient connection with the base plate of the staple.

A projection 2O on the hinge 15 of the lock limits the pivotal movementl of the lat ter by engagement with the carrier.

The arml 19 has a slot`19a through which the staple passes and it is bifnrcated at its freeend to straddle the tongue 10 of the lock support. f

The arm is depressed by the carrier when the lock is connected with the staple and provides a support for the hasp 6 which when the lock is subsequently returned to its inoperative position at the end of the tongue, is thrown upwardly by the move4 ment of the arm to facilitate its removal from the staple.

In the operation of my invention the hasp is as usual placed upon the staple after which the spring arm which by engagement with the lip 18 of the carrier secured the latter in its inoperative position at the end of the slideway, is depressed to release the carrier.

After the carrier has been placed adjacent to the staple as shown in Figure 2, the hinge lock is adjusted to embrace one of the legs thereof and the shackle of the lock is projected by the action of the key on the oper-y ating mechanism of the same.

The parts of the hasp lock are in this manner securely locked together and can be unfastened only by retraction of the shackle of the look through the medium of the proper key.

After the lock has been opened it is lifted from engagement with the sta-ple and the carrier is moved rearwardly along the tongue until it again occupies'its cxtreme position thereon as shown in Figure 1.

VDuring the rearward movement of the carrier the spring arm moves upwardly by its inherent resilience and lifts the hasp to facilitate its removal from the staple and after the carrier has reached its position at the end of the slideway the arm by engagement with the lip 18 at the forward cnil thereof, cooperates with the spring-catclr 1'? to hold the carrier in its adjusted position as hereinbefore explained.

Having thus described my improved hasp lock in its preferred form, its advantages will he readily understood. The lock being Lacasse staple after the hasp has been separated therefrom.

The sliding and pivotal movements of the lock allow of its adjustment to its operative position by finger pressure and the n provision of the spring arm facilitates the re moval of the hasp from the staple and moreover secures the lookin its adjusted position when separated from the other members of the fastening. f V

The modified construction illustrated Yin Figures 5 to of the drawings is particularly adapted for use on flexible straps, such as those employed in fastening mail sacks and the like, and it diers fromv the first described construction mainly in that tho slideway upon which the lock has its movement is pivoted as well as the lock itself.

The principal object of this arrangement is compactness of construction which when the hasp lock must necessarily occupy a limited space as on a mail sack7 is an obvious essential. p

The lock support in the modified construction consists of an arm 21 formed at an angle to the base plate of the staple and provided at its extremities with knuckles for the pivotal connection of thev slideway and the lock. l

The slideway consists of a plate 22 formed integrally with a short stem 23 by meansof which it is pivotally connected with one of the knuckles of the arm.

The plate is loosely fitted in a longitudinal recess 24C at the bottom of the lock and 110 its stem passes through a slot in the lower surface of the saine to permit of a linear movement of the lock upon the plate.

The pivotal connection of thelock with they arm of the support is established 115 through the intermediary of a short link 25 connecting the otherl knuckle of the arm with a corresponding` knuckle at the end of a bracket 26 extending downwardly from the en d of the lock.

rlhe device for lifting` the hasp consists in this form of my invention of a lever 2T which is pivoted upon the pintle of the hinge connection of the slideway 22.

One of the arms of thelever is positioned 125 to engage the underside of the hasp` after it is placed upon the staple and its other arm is disposed to be engaged by the lock when it turns about its pivot'to its inoperative position.

A spring-catch Q8 on the lock cooperates with the knuckle at the lower end of the arm of the support to hold the lock in its adjusted position when separated from the staple as shown in Figure 7, and the catch 28 is preferablwv positioned to engage the arm of the lever when the fastening is closed as illustrated in Figure 5.

The staple and the lock-support are conjointly mounted at an end portion of the flexible strap 9,9 to which the hasp-lock is applied, while the hasp is pivotally connected at the opposite end ot the same by means of a link 30.

Inasmuch as the operation ot the modified form oi the hasp lock is similar to that of the first-described construction, no further explanation is deemed necessary.
